Problems solved by technology

Marine biofouling will increase the navigation resistance of ships, lead to accelerated metal corrosion, block seawater pipelines, reduce the service life of marine equipment, and affect the aquaculture industry, etc.
So far, coating anti-fouling coatings is still the most economical and effective measure to prevent marine organisms from adhering. Anti-fouling coatings can keep the immersed parts smooth and free of dirt. At present, they are mainly used in ships and marine structures in seawater and fresh water. However, the current antifouling coatings have low hardness and are easy to be bruised and scratched during use, and their antifouling and antibacterial properties are not good, and the adhesion inhibition effect on microorganisms is not good. very ideal

Abstract

The invention discloses a marine modified silicone-acrylic resin antifouling antibacterial coating. Raw materials of the coating comprise modified silicone-acrylic resin, chlorosulfonated polyethylene, teflon, a vinylidene fluoride-hexafluoropropene copolymer, nano-silver, carbon nanotube, carbon fiber, nano-sized iron oxide, nano-zinc oxide, kaolin, lanthana, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, PTPB, 4,5-dichloro-2-n-octyl-3-isothiazolinone, trimethyl silicone oil, a coalescing agent, a dispersant, an antifoaming agent, a corrosion inhibitor, a leveling agent and a thickening agent. The marine modified silicone-acrylic resin antifouling antibacterial coating has high hardness and good antifouling property and antibacterial property, and has an effect of inhibiting adhesion of multiple marine organisms when in use.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special modified silicone acrylic resin antifouling and antibacterial coating for ships. Background technique [0002] There are a large number of microorganisms, marine plants and marine animals in the ocean, which will adsorb on the metal surface and grow and reproduce on the metal surface. Since human beings engaged in marine activities, the problem of marine biofouling has been a major problem that has restricted the development and utilization of marine resources. Marine biofouling will increase the resistance of ships, lead to accelerated metal corrosion, block seawater pipelines, reduce the service life of marine equipment, and affect the aquaculture industry. So far, coating antifouling coatings is still the most economical and effective measure to prevent marine organisms from adhering. Antifouling coatings can keep the immersed parts smooth and free of dirt. At pres...
